Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X160S-08A
The AirTAC Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X160S-08A is a genuine double-acting profile-type cylinder with a Ø50mm bore, 160mm stroke and a built-in 4M210-08 5/2 solenoid valve — it switches itself from one coil signal, so no separate remote valve or extra plumbing is needed.

About the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X160S-08A
The SAUF50X160S-08A is a double-acting profile cylinder with a built-in AirTAC 4M210-08 5/2 solenoid valve on the cap. One AC220V coil signal drives the actuator, eliminating remote plumbing and saving a manifold slot. The extruded aluminum barrel is shorter than an ISO 15552 cylinder of the same bore. It features a 1/4" valve port, 1/4" cylinder port, and a piston magnet for CMSG/DMSG/EMSG switches.
The integrated valve flows 16 mm2 (Cv 0.89) at up to 5 cycles per second. Although the cylinder body rates to 1.0 MPa, the assembled unit operates within the valve's 0.15-0.8 MPa window. At 0.5 MPa it delivers 982 N push force, giving a computed safe working load of roughly 589 N and a vertical lift capacity of about 50 kg with a 2:1 margin.

The cylinder rates to 1.0 MPa but the built-in valve operates 0.15–0.8 MPa, so run the assembled SAUF at 0.15–0.8 MPa. Default: rod retracts when the coil is energised (reconfigurable to extend). Specs follow the official AirTAC SAUF datasheet. Port options: PT / G.
Theoretical Output Force (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 N | — |
Sized within the valve's 0.15–0.8 MPa range. Actual usable force is lower than theoretical due to friction and back-pressure.

SAUF does not hold its load without air — the valve routes air, it is not a lock. For a held load, add an external rod lock or a pilot-operated check valve.
Where the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X160S-08A Is Used
Decentralized Clamping
Ideal for a multi-station machining line where each clamping point needs independent control without routing tubes back to a central manifold.
Inline Diverters
Perfect for conveyor sorting gates that require rapid, localized actuation at up to 5 cycles per second without complex air plumbing.
Package Stops
Suits decentralized packaging lines where individual stop gates operate on single coil signals, saving manifold slots and install time.
Is the Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X160S-08A the Right Choice?
Size by comparing the 50 mm bore (982 N push at 0.5 MPa) against the 40 mm (628 N) and 63 mm (1559 N) neighbors. Verify the AC220V terminal entry and PT threads match your control scheme. The default action retracts the rod when energized, but you can reconfigure it to extend by repositioning the valve. Always size force within the 0.15-0.8 MPa valve limit, not the 1.0 MPa cylinder rating. The built-in valve routes air and is not a load lock; add an external rod lock or pilot-operated check valve to hold a load. For this 160 mm stroke, ensure adequate side-load guidance.
Quick checklist
- ✓ Force at 0.15–0.8 MPa
- ✓ Coil voltage matches panel
- ✓ Terminal vs grommet entry
- ✓ Retract- or extend-when-energised
- ✓ Load-holding → external rod lock
Airtac SAUF Series Valve-Mounted Air Cylinder SAUF50X160S-08A FAQ
It uses a built-in 4M210-08 valve (1/4" port, Cv 0.89, 5 cycles/sec) on an AC220V terminal coil. The 50 mm bore pushes 982 N and pulls 825 N at 0.5 MPa. Despite the cylinder body rating of 1.0 MPa, you must size force within the assembled valve's 0.15-0.8 MPa operating window.
By default the rod retracts when the coil is energized, but you can reposition the valve to extend-when-energized. The 5/2 valve only routes air; it is not a load lock. If you need to hold a load on air loss, install an external rod lock or pilot-operated check valve.
